Honeywell MC-TDOY23 51204166-175 Experion 16-Channel Digital Output Board
Product Overview
The Honeywell MC-TDOY23 (Part Number 51204166-175) is a professional-grade 16-channel Digital Output (DO) Terminal Board designed to facilitate field terminations for Honeywell Experion PKS, TDC 3000, and High-Performance Process Manager (HPM) architectures. Functioning as a Field Termination Assembly (FTA), this board serves as the critical physical interface between the system's I/O processors and field-level actuators. It effectively manages discrete 24V DC on/off signals to drive solenoid valves, interposing relays, and motor starters. The MC-TDOY23 is built to maintain signal integrity in high-density industrial control cabinets, providing a structured wiring platform that simplifies both initial commissioning and long-term system maintenance.
